US space agency NASA said on Thursday that its Wide-field Infrared Survey Explorer (WISE) telescope has discovered a remote galaxy that shines with the light of more than 300 trillion suns, making it the most luminous galaxy ever found.

British astronomers have found out the answer to an astronomical mystery -- how do galaxies die? Evidence shows that they are "strangled to death", which occurs after galaxies are cut off from the raw materials needed to make new stars.

After searching 100,000 galaxies for signs of highly advanced extraterrestrial life, a team of scientists using observations from NASA's WISE orbiting observatory has found no evidence of advanced civilizations in them.

As two galaxies enter the final stages of merging, their supermassive black holes form a “binary” or two black holes that are gravitationally bound to one another. Now, astronomers from University of Maryland have found direct evidence of a pulsing quasar which may substantiate the existence of black hole binaries.
